Beatriz Bonilla da Costa's childhood is largely unknown. At some point, she was an amateur model in Rio de Janero before becoming a showgirl and stage performer. For reasons unknown, she also became an undercover agent for the Brazilian government. During one of her mission, she was exposed to a pyroplasmic explosion and after surviving, she discovered that she had the power to exhale green flames.
